Erchonia Corporation Wins Default Judgment in Green Laser Patent Case

Case Overview

In a decisive outcome for medical device patent holders, the U.S. District Court for the Northern District of Illinois entered a **default judgment and permanent injunction** against multiple unnamed online sellers in *Erchonia Corporation LLC v. The Partnerships and Unincorporated Associations Identified on Schedule A* (Case No. 1:25-cv-10560). The ruling, issued January 21, 2026, just 140 days after filing, permanently bars defendants from manufacturing, selling, or advertising the **LuxMaster Slim, Maxlipo Master, and Glaser** green laser devices — products alleged to infringe two Erchonia patents covering low-level laser therapy (LLLT) technology.

The case is a textbook example of an increasingly common enforcement strategy: using Schedule A mass-defendant litigation to swiftly neutralize offshore marketplace sellers on platforms like AliExpress, Alibaba, and DHGate. For patent attorneys, IP professionals, and R&D teams operating in the medical device and aesthetic laser space, this outcome carries significant strategic weight.

The Parties

The Patents at Issue

Two U.S. patents formed the basis of Erchonia’s infringement claims. Both patents relate to **green laser technology** applied in non-invasive body contouring and aesthetic medical procedures — a commercially valuable and competitive market segment.

• • US7947067B2 — Covers foundational laser therapy device architecture and methodology
• • US9149650B2 — Covers refined LLLT system configurations and treatment protocols

Litigation Timeline & Procedural History

The case was filed in the **Northern District of Illinois**, a venue frequently selected for Schedule A patent enforcement actions due to its established procedural familiarity with e-commerce IP cases and its capacity to issue emergency ex parte relief, including temporary restraining orders and asset freezes.

Presiding over the matter was **Chief Judge Andrea R. Wood**, whose court handled the case efficiently from filing through final judgment in fewer than five months — a notably fast resolution consistent with uncontested default proceedings.

The 140-day duration reflects the absence of any substantive defense. When defendants fail to appear or respond, courts can proceed to default judgment without the procedural overhead of claim construction hearings, expert discovery, or trial. The $10,000 bond posted by Erchonia — standard in preliminary injunction proceedings — was ordered released back to plaintiff upon final judgment.

The Verdict & Legal Analysis

Outcome

Chief Judge Andrea R. Wood **granted Erchonia’s Motion for Entry of Default and Default Judgment in full**, entering a **permanent injunction** against all defaulting defendants. The court’s order:

• Deemed all non-appearing defendants **in default**
• Permanently enjoined defendants from making, using, selling, or offering for sale the LuxMaster Slim, Maxlipo Master, and Glaser products
• Extended injunctive reach to **third-party platform providers**, including AliExpress, Alibaba, DHGate, Made-In-China, and Aimylin.com
• Required compliance within **seven calendar days** of order receipt
• Ordered the $10,000 preliminary injunction bond released to Erchonia

No specific damages award was disclosed in the available case data, which is not atypical in default judgment proceedings where the primary remedy sought is injunctive rather than compensatory.

Verdict Cause Analysis

The legal basis was a straightforward **patent infringement action** under 35 U.S.C. § 271. Because defendants failed to appear, the court accepted Erchonia’s well-pleaded allegations as admitted, consistent with the standard applied under Federal Rule of Civil Procedure 55(b). There was no contested claim construction, no validity challenge, and no infringement rebuttal.

The strategic significance lies not in legal complexity but in **procedural precision**: Erchonia’s legal team structured the complaint and default motion to satisfy all elements required for injunctive relief — likelihood of irreparable harm, inadequacy of monetary damages, balance of hardships, and public interest — thereby securing the broadest possible enforcement mechanism.

Legal Significance

While default judgments carry **limited precedential value** for substantive patent law, this ruling is procedurally instructive for several reasons:

• Third-party platform orders — The court’s direct targeting of AliExpress, Alibaba, DHGate, and similar platforms as enjoined third parties reinforces the viability of this enforcement mechanism under *Tiffany v. eBay* progeny, extending injunctive reach beyond named defendants to the commercial infrastructure enabling infringement.
• Schedule A mass-defendant structure — The case exemplifies how patent holders can efficiently consolidate claims against diffuse offshore seller networks, reducing per-defendant litigation cost while maximizing marketplace disruption.
• Asset discovery mechanism — The order’s provision allowing Erchonia to serve supplemental proceedings via email for subsequently identified accounts reflects courts’ adaptation to the realities of anonymous e-commerce enforcement.
